摘要： 随着水资源的日趋短缺，生物节水在节水农业发展中的地位越来越受到重视。近年来, 随着分子标记技术和数量性状统计分析方法的改进，对调控水分利用效率等复杂数量性状的位点进行作图和定位的研究很多。本文综述了鉴定小麦高WUE的常用指标以及相关性状的QTL定位研究进展，并对目前在QTL定位研究中存在的问题及发展前景进行了探讨。

Abstract: Drought stress is the first constraint affecting wheat production remarkably in the world.In the past decades, with the development of molecular marker technology and quantitative statistical methods, a large number of papers had reported much about mapping and location of complex quantitative traits, such as water use efficiency(WUE).The evaluation standards for high WUE and QTL(Quantitative trait loci) mapping on wheat chromosomes were summarized. Furthermore, problems and prospects of QTL mapping were discussed in this review.It would benefit researches involving in QTL mapping and breeding for drought tolerance in wheat.
